Description
R. WAHLBECK May 6, '1952 SYRINGE Filed May 15, 1949 INVENTOR AE W/lf/ 556x Patented May 6, 1952 UNITED s'rATEs PATENT OFFICE SYRINGE Ragnar Wahlbeck, New York, N. Y. Applicationiuay 18, 1949, serial No. 93,091 1 claim. (C1. 128-2311 This invention relates to new and useful improvements in catheters.
The dominating object of this invention is the construction of a catheter which may be folded to a very small size so that it may be carried in a small container.
More particularly, it is proposed to characterize the new catheter by a normally flat, soft rubber bag having a neck portion, a soft rubber nozzle of thicker rubber than said bag and having an inlet end portion, and a pair of connectors for connecting said bag and nozzle together.
It is proposed that one of the connectors be tightly mounted in the neck portion of the rubber bag and the other connector tightly mounted in the inlet end portion of the nozzle in order that the nozzle may be connected with said bag and disconnected from said bag merely by connecting and disconnecting said pair of connectors.
This invention contemplates that said rubber bag be made from thin rubber, preferably by dipping. It is also proposed that the neck portion be provided with a beaded edge for more securely engaging and holding said connector. It is also proposed that said connector be provided with a beaded portion engaging beneath said beaded edge in order to securely hold these parts together.
The invention also contemplates to construct the connectors with tapered portions which may be forced together for inexpensively providing efficient connectors for the catheter.
Preferably, the soft rubber bag is provided with folded side portions which may be opened when said bag is opened in order to increase the capacity of the bag.
The invention also contemplates the provision of a small waterproof flexible case into which said nozzle and bag may be engaged when disconnected from each other and folded.
Fig. 1 is an elevational view of a catheter cona structed in accordance with this invention.
Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1.
Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig. h1. i
Fig. 4 is a fragmentary enlarged Vertical sectional view taken on the line 4-4 of Fig. 1.
, Fig. 5 is an elevational view of one of the .connectors used in the catheter, but illustrated per se.
Fig. 6 is an elevational view of another connector.
Fig. 7 is an elevational view of the flexible case for the catheter, portions thereof being broken away to disclose the interor construction.
The catheter, in vaccordance with this invention, includes a normally flat soft rubber bag l having a neck portion l I. A soft rubber nozzle |2 of thicker rubber than said bag IO is provided with an inlet end portion |3. A pair of connectors |4 and |5, adapted to be connected with each other and disconnected from each other, is associated with said bag Hl and nozzle |2. More particularly, the connector |5 is tightly mounted in the neck portion H and the connector [4 is tightly mounted in the inlet end portion l3 in order that said nozzle |2 may be connected with said bag IO and disconnected from said bag lfl merely by connecting and disconnecting said pair of connectors |4 and 15.
The neck portion ll is provided with a beaded edge IG. The connector |5 is provided with a complementary beaded portion |1 adapted to engage beneath the beaded edge l6 in order to securely hold these parts together, see particularly Fig. 4. The connector |4 is provided with a tapered end portion 18 adapted to tightly engage into the inlet end portion |3 of the nozzle l2. The connector 14 is also provided with a tapered end portion |9 engageable in a complementary tapered opening 20 formed in the connector l5. A passage 2| engages through the connector Ill through which liquid may fiow.
The bag IO is provided with folded side portions 23 which may be opened When said bag is opened in order to increase the capacity of the bag. The outer end of the nozzle 12 is provided with a tip portion 24 having orifices 25.
A small waterproof flexible case 21 is provided into which the nozzle |2 and bag III may be engaged when they are disconnected from each other and folded into a small Compass. This case 21 is provided with a fiap cover 28 adapted to be held closed with a snap fastener 29.
The operation and use of the catheter may be understood from the following. In Fig. 1 the asoaoss catheter is illustrated with the nozzle 12 mounted in position upon the bag IO. However, the bag IO is illustrated empty and arranged With the folded side portions 23 folded inwards. The nozzle IZ may be removed merely by pulling it away from the bag IO so that the connector |4 disengages from the connector l5 which maintains its position in the mouth of the bag IO. The bag may be filled With suitable fluid which will open up the folds 23 so as to receive a maximum quantity of liquid. The nozzle |2 is then connected with the bag |0 merely by engaging the connector |4 with the connector 15. The catheter is used in the usual way.
When the catheter is not being used it may be stored in the case 21. This maybe done by first pulling oif the nozzle |2 from the bag IO. The bag IO may be suitably cleaned because of the large passage through the connector |5. The bag IO may be folded or rolled into a small compass so as to fit into the case 21. The nozzle |2 is rolled or bent so as to also fit into the'case 2'1.
'While I have illustrated andV described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction hereinV disclosed and the right is reserved to all changes and modificati'ons coming Within the scope of the invention as defined in the appended claim.
Having thus described Vmy invention, What I claim as new and desire to secure by United States Letters Patent is:
A catheter, comprising a normally flat soft rubber bag having a neck portion,V a soft rubber nozzle ofthicker rubber than said bag and having an inlet end portion, a pair of connectors, one of said connectors having a tapered projecting end portion and the other having a tapered socket portion for receiving and frictionally holding said projecting end portion, and one of said connectors being tightly mounted in said neck portion' and the other being tightly mounted in said inlet end portion.
